With all the turmoil that preceded the games involving the International Olympic Committee scandals—the host country selection proc...

An Adaptive RIO (A-RIO) Queue Management Algorithm

In the context of the DiffServ architecture, active queue management (AQM) algorithms are used for the differentiated forwarding of packets. However, correctly setting the parameters of an AQM algorithm may prove difficult and error-prone. Besides, many studies have shown that the performance of AQM mechanisms is very sensitive to network conditions. In this paper we present an adaptive AQM alg...

Olympic Medals, Economy, Geography and Politics from Sydney to Rio

T he paper uses Heckman model to examine the statistical importance of over 140 independent variables on the Olympic performance of all countries participating in the Summer Olympic Games from Sydney 2000 to Rio 2016. We find that countries which export more products have a higher likelihood of winning an Olympic medal than their counterparts exporting fewer products, and explain why...

Rio Grande Gummosis

Young Valencia orange trees were grown for three years in large outdoor sand cultures on complete nutrient solu tions that varied differentially only in the amount of boron. Three rates of boron were applied to single-tree plots. The plots were replicated four times. No difference in tree size resulted from the differential treatments. Rather large differences in the boron content of the leaves...
